Hi,
This is a known issue. To circumvent the problem you could try:
1. Open the drawing as well as the Design Criteria Editor
2. Open any other Design Criteria File other than the IRC Design Standards
3. Note that under Minimum Radius tables speeds are in increasing order
4. Now open the IRC Standard Design Criteria File
5. Note that under Minimum Radius tables Design speeds are in decreasing order
6. Note the values elsewhere and reset the values in the rows in increasing order
This should stop the exclamation mark to disappear
Thanks and Regards,
Vivek
